よくある思い込み

six.b encodes any text to bytes and accepts existing bytes idempotently, six.u coerces bytes to str, and six.byte2int coerces integer inputs while defaulting empty bytes to zero

このサンプルの作者が、ここで開発者やモデルが期待するであろうこととして記録したもの。下の契約が実際に実行されたものだ。

コントラクト

• six.b strictly encodes strings using latin-1 raising UnicodeEncodeError on code points above 255 and AttributeError on existing bytes rather than coercing via UTF-8 or acting idempotently
• six.u is an identity function on Python 3 that returns bytes unchanged without text coercion
• six.byte2int is mapped to itemgetter(0) which raises IndexError on empty bytes, raises TypeError on integers, and returns single-character strings when passed str
• six.indexbytes raises IndexError on empty byte sequences while supporting negative indexing on populated byte sequences
• six.ensure_binary and six.ensure_text strictly reject non-str non-bytes buffer types such as bytearray, memoryview, and None with TypeError
• six.get_function_defaults and six.get_function_closure return None rather than empty tuples when defaults or closures are absent
• six.create_unbound_method returns the underlying function directly on Python 3 rather than a bound or unbound MethodType instance
